Brookfield Office Properties Inc. is planning an $11 million renovation of 799 Ninth St. NW as the building’s main tenants vacate for new space in D.C.’s NoMa neighborhood.

Brookfield Senior Vice President Greg Meyer said he believes the renovations will appeal to law firms and other tenants seeking space near Mount Vernon Square, particularly given the success Hines and Archstone have had attracting new firms to their CityCenterDC development at the old convention center site nearby.

“If it had been a fringe location starting farther east, we would have looked at doing something at a lower price point, but we wouldn’t have paid as much to buy the building if it were,” he said.

Brookfield is marketing space in the 202,725-square-foot building at a rental rate of between $46 and $51 per square foot.

Brookfield plans to start interior demolition work in January and begin major renovations in March. The improvements are slated to include streamlining the building’s lobby, adding a rooftop terrace, a new fitness center and other cosmetic improvements. The work is slated to take about five or six months to complete.
